Leather, Rubber & Urethane Drive Belts
By Tom Neuhaus
I have been experimenting with urethane belts myself. At first
blush these seem to be a great alternative to leather and rubber.
For one, the urethane belts don't slip. They also are great if
you have a three-step pulley to change speed on a 10-tune roll.
My biggest issue with them is that they vibrate while running. On
one machine I restored it vibrated itself off the pulley. On a
Coinola "C" I restored the customer called and had the urethane
belt replaced with leather. We could actually hear the belt vibrate.
I included a YouTube link that will show what I am talking about:
